The indocyanine green angiography (ICG angiography) is a clinical test performed by an eye care specialist. This test is used to detect any abnormal blood vessels that are present in the choroid. The choroid is the layer of blood vessels that are under the retina. Indocyanine is a harmless green dye. It gives off infrared light. When the indocyanine is injected into the bloodstream, it travels through the veins to the blood vessels in the eye. A video camera that is connected to a computer picks up the infrared light and takes a picture of the blood’s circulation. This way the doctor can look for any abnormalities.
After the test, the dye is removed through the liver. This test poses very little risk but, some people may have a mild allergic reaction. The indocyanine green dye contains iodine and should not be used in patients with iodine allergy or those with kidney failure.
With the ICG Angiography, abnormal blood vessels can be detected. These are associated with eye conditions such as macular degeneration. This eye condition can cause bleeding, scarring, and/or vision loss.
If you need to have this test done, your eye doctor at Boston Vision will tell you how to prepare for this test. If you are experiencing any issues with your eyes, don’t wait to get an examination.
